When a defense contractor was having difficulty with a gold optical coating for their mission critical part, they approached EMF. The company had been working with an EMF competitor who could not meet the company’s stringent specifications. The defense contractor urgently needed an optical coater who could turn around the product quickly with quality that would typically take weeks or months to achieve over multiple iterations.

EMF’s integrated optical coating development and manufacturing

Since EMF’s development and manufacturing are housed in the same place, their development team has the ability to test new coating chemistry and processes on production-level coating chambers. This ensures a seamless transition from development formulations and processes to final production products. Because of this integration, EMF was able to quickly adjust the processes and formulations of the gold coating, so that the final production level product met the exact same specifications as the development prototypes from the defense company. Once the process had been perfected, they could immediately scale up into production, which shortened the turnaround time by weeks.

Mission accomplished

Because of EMF’s expertise and responsiveness, the defense contractor was able to meet their own demanding production schedule, despite major delays caused by the previous coating company.
